Assuming a Method Int FindMax(int Array[ ],Int Last)that Returns the Subscript of the Subscript

Assuming a method
Int findMax(int array[ ],int last) that returns the subscript of the largest value in the portion of an array whose elements are at 0 through last (inclusive) ,a method for sorting an array in ascending order can be written as follows:
Void sort(int array[ ]) {
For (int last = array.length-1;last >=1;last --) {
Int maxPos = findMax(array,last) ;
// Code is missing
}
}
If a method
Void swap(int array[ ],int pos1,int pos2) can be used to swap the contents of two array entries,then the logic for the missing code is

A) swap(array,maxPos,last) ;
B) swap(array,maxPos,last-1.;
C) swap(array,array[maxPos],array[last].;
D) sway(array,array[maxPos],array[last-1].;
